摘要

以偏重亚硫酸钠(Na2S2O5) 和高锰酸钾(KMnO4)为原料, 通过W/O乳状液模板技术制备了纳米MnO2微球. 用SEM、TEM、XRD、FT-IR等手段对产品的形貌、物相和成分进行了表征. 结果发现用本方法制得的纳米MnO2微球, 大小基本均匀, 球形规整, 纯度较高, 且具有较高的反应活性. 结合实验事实和产品特性, 初步探讨了纳米MnO2微球的形成机理.

Abstract

Nanometer manganese dioxide microspheres were prepared from sodium pyrosulfite acid and potassium permanganate via using W/O emulsions as template. SEM, TEM, XRD and FT-IR were used to characterize the MnO2 micropheres. The SEM and TEM images showed that the average diameter of the MnO2 micropheres was about 150nm. The XRD analysis indicated that the MnO2 micropheres was of non-crystalline and active. According to the experimental facts and characteristic of the products, the formation mechanism of the microsphere was discussed.
